Half the batch of BTY cells were dead on arrival!
(N.B. An earlier purchase of BTY AAA cells were excellent, but these were dreadful!)
The "green" cells were reliable, but who wants 450mAh storage (2600 claimed!).

Me? - I will be buying Vapex Instant for nearly all purposes in future.
They are a low self-discharge type, sold at a good price.
The UK website is at www.vapextech.co.uk

Added 31 May 2014....My Eneloop batteries have a low failure rate.The Vapex have had quite a few failures.
Buy them at BatteryLogic.
